- Renewed October 31, 1933 6 Claims. (Cl. 3063) My present invention relates to adjustable sweep beneath articles of furniture for the reason brushes and more particularly to devices of the that the handle, being rigid, cannot be lowered general character specified which are used for to permit the same to pass beneath the furniture. sweeping the floor. It is one of the objects of However, the present invention eliminates 5 my invention to provide an adjustable brush these disadvantages by providing an adjustable which is simple in construction, easy and ecobrush wherein the handle may be completely ronomical to fabricate and assemble, which may tated in either direction with respect to the brush be used under circumstances where ordinary body and, if desired, the handle may be lowered brushes cannot be used, and which are exceedso as to be in almost a horizontal plane so ingly effective in cleaning normally inaccessible that the brush may be used to sweep beneath 65;

It is, however, to be erence to the drawing illustrating the same, the 1 clearly understood that the adjustable brushesof numeral 10, generally designates a rectangular the present invention are not to be limited to the block which constitutes the brush body.

Hitherto, tion of the rod 20 is threaded at 23 and is rebrushes of the class referred to in the opening ceptive of a nut 24 adapted to retain the cup paragraph of this specification have consisted, 15 in position within the bore 13.

for the most part, of a brush body in the form Rotatably mounted on the rod 20- and wiping- 100 of a block which carried a multiplicity of bristles. 1y engaged on the bearing surface 18 of the flange Rising from the brush body, in a rigid manner, 17 is a disk 25 provided with the oversized centhere was provided a handle at an angle of aptral opening 26 and a tongue 27 struck downproximately 45. The disadvantages of using wardly therefrom so as to engage the inner sursuch a device are obvious. There are many face of the flange 17 to guide the disk during 105 places, such as corners, which cannot be reached its rotation, the space providedby the struck properly with a brush of the type just referred down tongue presenting a notch 28. Opposite the to inasmuch as the handle cannot be rotated notch 28, and on the other side of the central with respect to the brush body. In addition, with opening 26, the disk 25 is provided with a recbrushes of this type, it is impossible to properly tangular slot 29. 1 10 Thus, while the cup 15 is retained rigidly connected with the block 10, the disk 25 may be completely rotated in either direction with respect to the cup.

I now provide an angle-adjusting member so that in addition to the handle, which will later be described, being rotatable with respect to the brush body, the same may also be raised or lowered as circumstances require. Such'member, generally designated by reference character 30, is provided with an oversized opening 31 by means of which the same is rotatably engageable 'on the rod 20, the front end of the member 30 being provided with a lug 32 adapted, under certain conditions, to be engaged in the notch 28 of the disk 25. Opposite the lug 32, and on the other side of the opening 31, the member 30 isprovided with a leg 33 the lower end of which-isprovided with a contact surface 34 by means of'which the member 30 may be supported in its raised position, as willlater be seen.

.Themember .30 is retained ineither ofits adjustable positions by means of .auwing nut 35 and washer 36 which are engageable on'thethreaded portion 23.0fthe rod 20. The member 30'is completed by a handle-carrying portion 30' having atthe outer end thereof a thread portion 3'7 of reduced size which is engaged in a cylindrical bushing 38 supported by a 'metallic sleeve 39 which, in turn, is carried 'by an' elongated wooden handle 40. i

This completes the-description of the aforesaid illustrative embodiment of the adjustable brushes of the present invention. While the mode of assembly and use of the same are thought to be obvious fromthe foregoing description, the same may bebriefiy summarized asfollowsx After providing theblock with the'bristles 12, the cup is lowered into the bore '13 and thereafter the rod carrying the washer '22.is inserted through the bore 14 of the block 10 and through the cup 15 by way of the oversized opening 19. The nut 24 is then-secured in place to hold the cup 15 rigidly with respect to theblock 10. Thereafter the disk 25 is'mounted uponthe rod 20 so that the same wipingly contacts the bearing surface 18 of the flange 1'7 of the cup 1-5, the tongue 2'? engaging the inner surface of the flange 1'7 so-as to guide the disk 25 during its rotation. The angle-adjustingmember 'is then mounted upon the rod 2 0 through the opening 31 so that the lug'32 will engage inthe notch 28 andthe surface 3'4of theleg 33 will contact the upper surface of the disk 25 adjacent the outside of the slot '29. Finally the washer 36 is positioned on the rod 20 and the ensemble is held in the adjusted position shown in Fig. 3 of the drawing by the wing nut 35. Thebrush is now ready for ordinary use, the-handle being disposed at an angle of approximately 45 with respect to the brush body. In view of the engagement between the lug 321 and the member' 30 and the notch 28 of the disk 25, theentire handle 40 may be completely rotated in either direction'together with the disk 25 with respect to the cup 15 and hence the brush-body 10. If it is found-necessary to sweepbeneath anarticle of furniture, etc. and the angle at which the'handle 40 is disposed will not permit the brushto bemoved beneath the furniture, the wing nut may be loosened, the member 30 slightly raised on'the rod 20 so that the-lug 32 will becomedisengaged from the notch 28 and the leg'33 will drop into-the slot 29 and extendwithin the cup 15. Upon retightening the wing nut-35, the brush will be in the position shown in Fig. 4 of the drawing, at which time the handle will extend substantially horizontally thus permitting the brush to be readily moved beneath the article of furniture. In this position, too, by reason of the engagement of the leg 33 in the slot 29, the entire handle may be rotated in either direction with respect to the brush body.

This completes the description of the mode of employing and operation of the aforesaid illustrative embodiment of the present invention. It will be noted from all the foregoing that the adjustable brushes of the present invention readily overcomethe disadvantages of the prior art set forth in earlier-portions of this specification and afford certain advantages likewise discussed in earlier portions of this specification. Other superiorities and advantages of the devices of the present invention will be readily apparent to those skilled in the art to which the present invention relates.
